ASRock 970 extreme3 r2 black screen bios update

Hi,
I have a 10 years old pc build with an asrock 970 extreme3 r2 motherboard.
About 3 weeks ago I've bought new DDR3 RAMs and before format HD and reintalling windows, I tried to update the bios from 1.0 (never updated before) to the last bios version downloaded from the mobo official webpage.
After it finished the update it restarted and got a light blue windows screen (like the one for windows recovery) with some kind of error and an option to reboot windows (I dont remember well, I should have taken a shoot...I know).
After restart endless black screen...
After 10 minutes of waiting I've decided to force the shut down, because the simple pressure of power buttom didnt worked as always.
Tried to restart, and press keys to open the bios menu but endless black screen.
Next I've tried to restart using only first RAM....nothing.
Then, after a mix of rage and panic I tried to remove the cmos battery for 10-15 minutes...nothing, then for 30 minutes and nothing. Next I tried cmos reset with jumper 2 or 3 times as explained in the istructions and following all the security warning.
As last, last week, I tried to replace the bios chipset with an equal one, placing it in the same direction as mine...but nothing changed....endless black screen.
Then I start thinking that maybe was my gtx 1050ti problem, but this morning I tried it on another pc and it works perfectly.
At this point I don't really know what it could be.
I want to specify that PC, after new RAMs replacement, worked as good as before.
So you can insult me asking me why did you update the bios?
Simply I didnt imagine that a bios update could cause this damage.
I dont know what's gone wrong, probably the wrong usb port, or probably I didnt default bios option before proceding...but I don't understand why it is not working even after changing the bios chipset, as, if I read well, it's replacing should resolve the problem to its root.
The only thing I'm thinking is that some other component has been corrupted.
If anyone have a possibile hints to get the solution (except throw the mobo in the garbage) I'm all ears.
If you need other specs just ask.
THank you.

Hi,

It seems like a power issue about new memory modules. What's the speed of your new memory modules? And, have you tried booting with only one of the old memory modules plugged in?

By the way, if you've left Clear CMOS jumper on 2_3 position, that may cause such behavior. If that's the situation, try putting it back to 1_2 position.

I doubt the BIOS chip is corrupted, so try booting with your original chip first. But, where did you get the extra BIOS chip? I might need one in the future for my tests.

You could check if the graphics card needs this Nvidia firmware update:

If the original BIOS had UEFI Secure Boot default to Off and the latest BIOS has UEFI Secure Boot default to On that might cause the graphics card problem.
